Java Timer Class Tutorial: Scheduling Tasks to Repeat at Regular Intervals | Timer and TimerTask

In this Java tutorial, we'll learn how to schedule a repeated task at a fixed interval using the `schedule(TimerTask task, Date firstTime, long period)` method of the Timer class. This method allows us to specify the first occurrence of the task and the interval between subsequent executions.

Here's a breakdown of the steps involved:

1. **Create a TimerTask**: First, we need to create a class that extends the TimerTask abstract class. This class will contain the code that we want to execute repeatedly at the specified interval.

2. **Override the `run()` Method**: Within the TimerTask subclass, override the `run()` method and include the code that you want to execute each time the task runs.

3. **Create a Timer Instance**: Instantiate a Timer object, which will be responsible for scheduling and executing tasks.

4. **Schedule the Task**: Use the `schedule(TimerTask task, Date firstTime, long period)` method of the Timer class to schedule the task. Provide the TimerTask instance, the first occurrence time (as a Date object), and the interval between subsequent executions (in milliseconds).

5. **Handle Exceptions**: Handle any potential exceptions that may arise, such as parsing errors or runtime exceptions.

6. **Run the Program**: Finally, run the program and observe the repeated execution of the task at the specified interval.

By following these steps, you'll be able to schedule a repeated task at an interval using the `schedule(TimerTask task, Date firstTime, long period)` method of the Timer class.
